Continued ecological impacts of invasive species on freshwater ecosystems is one of the main challenges confronting ecologists and decision makers in conserving biodiversity and ecosystem function today. Efforts to prohibit ...

Anthropogenic modifications of marine environments result from a variety of activities and have effects across social and ecological dimensions. Humans inhabit linked systems, where our actions such as resource extraction, ...

Residential shoreline and watershed development by humans are leading drivers of biodiversity loss in lake ecosystems that reduce abundances and diversity littoral invertebrates. Invertebrate biological and life history ...

Genetic analysis represents a powerful tool for informing management and studying adaptation in wild populations. For example, genetic tools can be used to delineate conservation units, assign individuals of unknown ...

This work explores (1) the potential for using marine reserves to manage data-poor fish populations, (2) the potential for marine reserves to influence the performance of commonly used stock assessment approaches relative ...

The research in this Ph.D. dissertation focuses on the relationship between fishery-dependent catch-per-unit-effort (CPUE) and abundance and how its use when assessing and managing fisheries may be affected by some of its ...

Global surface temperatures are warming at unprecedented rates and are expected to continue to warm for the rest of the century. Yet, we know very little about how freshwater ecosystems will respond to a warmer climate. ...

High mortality rates of Pacific salmon (Oncorhynchus spp.) in the nearshore ocean environment of the Columbia River (Northwest USA) is one of several key factors limiting recovery of these threatened and endangered fish. ...
